CY2018	us-gaap	Use Of Estimates UseOfEstimates	Use of Estimates. In preparing consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan and lease losses, the assessment for other-than-temporary impairment on investment securities and the fair value of certain financial instruments.

The Bank’s loan portfolio contains concentrations of credit in multifamily, single family, commercial, and home equity loans. The Bank believes its underwriting standards combined with its low LTV requirements substantially mitigate the risk of loss which may result from these concentrations.Credit Quality Indicators<span style="font-family:inherit;font-size:10pt;font-style:italic;">.</span><span style="font-family:inherit;font-size:10pt;"> The Company categorizes loans and leases into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans and leases individually by classifying the loans and leases as to credit risk. The Company uses the following definitions for risk ratings.</span><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Pass</span><span style="font-family:inherit;font-size:10pt;font-style:italic;">.</span><span style="font-family:inherit;font-size:10pt;"> Loans and leases classified as pass are well protected by the current net worth and paying capacity of the obligor or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner.</span></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Special Mention</span><span style="font-family:inherit;font-size:10pt;">. Loans and leases classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or of the institution’s credit position at some future date.</span></div><div style="line-height:120%;padding-bottom:8px;padding-top:8px;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Substandard</span><span style="font-family:inherit;font-size:10pt;">. Loans and leases classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans and leases so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.</span></div><div style="line-height:120%;padding-top:12px;text-align:justify;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Doubtful</span><span style="font-family:inherit;font-size:10pt;font-style:italic;">.</span><span style="font-family:inherit;font-size:10pt;"> Loans and leases classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.</span></div>The Company reviews and grades loans and leases following a continuous loan and lease review process, featuring coverage of all loan and lease types and business lines at least quarterly. Continuous reviewing provides more effective risk monitoring because it immediately tests for potential impacts caused by changes in personnel, policy, products or underwriting standards.
